This two-unit set pairs an F3A and an F3B, road numbers 307 and 505, and includes onboard DCC decoders with SoundTraxx Tsunami2 sound plus dual cube speakers to deliver authentic engine rumble, horn blasts, and bell tones in both DC and DCC operation. Realistic detailing includes see-through cab interiors, etched metal details, wire grab irons, directional LED lighting, and body-mounted McHenry scale knuckle couplers on RP25 wheels for smooth operation and prototype accuracy.\u003c\/p\u003e\n\t\u003cp\u003eBuilt on a heavy die-cast frame for traction and pulling power, these F3s feature a Genesis driveline with a 5-pole skew-wound motor for smooth, quiet operation, along with all-wheel electrical pickup and RP25 wheel contours for reliable tracking. They are DCC-ready with Quick Plug plug-and-play technology and a 21-pin NEM connector, and include trainline and MU hoses, windshield wipers, sanding lines, and a detailed fuel system. The minimum radius is 18 inches (22 inches recommended), making this SP F3A\/F3B set well suited for mid- to large HO layouts and ideal for capturing the distinctive bulldog-nose, 'covered wagon' styling of Southern Pacific's early diesel power.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Athearn (ATH)","offers":[{"title":"Default Title","offer_id":47844020289588,"sku":"ATHG19678","price":619.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/6653\/8292\/files\/ATHG19678.jpg?v=1779964637","url":"https:\/\/nankinhobby.com\/products\/athg19678","provider":"Nankin Hobby","version":"1.0","type":"link"}
